You're Invited | Community Information Session – Kalgoorlie VBESS

VSUN Energy and Australian Vanadium Limited warmly invites the Kalgoorlie community to a lunchtime information session to learn more about our proposed Kalgoorlie Vanadium Battery Energy Storage System (VBESS).

Hear about the proposed 50MW / 500MWh vanadium flow battery, and learn how the project could enhance energy security across the Goldfields while creating opportunities for local businesses, suppliers and the wider community.

📅 Monday 13 July
📍 Kalgoorlie Overland Motel
🕛 12:00 pm – 1:30 pm
🥪 Light lunch provided

This is an opportunity to ask questions, share your feedback and find out more about the project. We look forward to meeting with you.

A significant step forward for VSUN Energy and our partners.

VSUN Energy was pleased to mark the signing of a pre-bid agreement with Sumitomo Electric Industries, with Australian Vanadium Limited CEO Graham Arvidson and Sumitomo’s General Manager, Redox Flow Battery Division, Mr Kazuyuki Kamada coming together for the occasion.

The agreement brings together Sumitomo Electric’s globally proven vanadium flow battery technology with VSUN Energy’s project development capability and the broader Australian vanadium supply chain through Australian Vanadium Limited.

This collaboration strengthens VSUN Energy’s bid for the WA Government's proposed Kalgoorlie Vanadium Battery Energy Storage System and reflects a shared focus on delivering reliable, long-duration energy storage solutions at scale.

We look forward to continuing to work closely with Sumitomo Electric as the Kalgoorlie VBESS process progresses.

With the rapid growth of AI infrastructure new energy challenges are coming to the fore including power volatility.

Recent reporting by the ABC News on proposed data centre developments by Cloud Carrier highlights the scale of electricity required to support the AI economy. But the deeper issue for grids isn’t just the number of megawatts required it’s how those megawatts behave.

AI workloads don’t draw power in a steady, predictable way. They surge, idle and fluctuate continuously, this creates highly volatile load profiles that can place significant stress on local grids, feeders and substations. As larger facilities come online, managing power quality, ramp rates and grid stability will become a critical challenge for energy planners and data centre operators alike.

This is where vanadium flow batteries (VFBs) present a compelling solution.

Unlike conventional lithium-ion systems, which were designed primarily for short bursts of energy, VFBs are engineered for continuous cycling and endurance, making them well suited to smoothing the volatile power profiles created by AI infrastructure.

Positioned alongside data centres, long-duration flow battery systems can effectively act as power stabilisers, absorbing volatility in real time while supporting reliable, resilient energy supply.

As the AI economy accelerates, the conversation is shifting from simply how much power we generate to how stable and flexible that power must be.

Vanadium flow batteries offer a pathway to ensure that the infrastructure powering the digital economy remains stable, safe and sustainable.

A small town in the NSW Southern Highlands is watching the AI revolution take shape in its backyard, as plans emerge to build one of the state's largest gas-fired power stations to run a data-processing complex.

Big energy challenges need long-duration solutions and Western Australia is stepping up.

VSUN Energy, together with our parent company Australian Vanadium Limited, has submitted an Expression of Interest for the Kalgoorlie Vanadium Battery Energy Storage System (VBESS), a landmark project designed to strengthen energy resilience in the Goldfields and support WA’s clean energy future.

Our submission is built around Project Lumina, VSUN Energy’s modular, utility-scale vanadium flow battery architecture, purpose-designed for Australian conditions. Backed by local vanadium electrolyte manufacturing and a growing domestic supply chain, Lumina is engineered to deliver safe, reliable, long-duration storage at scale.

This project represents more than energy storage. It’s about:
• Reliable power for regional WA
• Local industry participation and skilled jobs
• Supporting the transition to a cleaner, more resilient energy system

We’re proud to be part of a proposal that reflects years of technical development, collaboration and commitment to Australian-made energy solutions. We look forward to the next stage of the WA Government’s assessment process.

Vanadium flow batteries are built for the demands of long-duration energy storage and they’re ready to play a much bigger role in Australia’s energy mix.

This video from Vanitec showcases why VFB technology stands apart: inherent safety, rapid response, deep discharge capability and an operational life measured in decades, not years. These attributes make vanadium flow batteries especially well-suited to grid, remote, and industrial applications, including hot and harsh environments.

At VSUN Energy, we’re focused on turning this proven technology into practical, Australian-ready energy storage solutions. From demonstration projects through to large-scale deployments, our work continues to show how VFBs can support reliable power, higher renewable pe*******on and resilient energy systems.

Australia is building its long-duration energy storage capability now and vanadium flow batteries are a key part of that journey.
